Breast sore - please give advice

Mia • 💍👱🏼‍♀️👧🏻👼🏼👼🏼👼🏼👧🏼👶🏼

So this is my third baby and I’ve never had sores on my breasts before. I’ve had thrush before and mastitis more than four times between all of my kids. But this is new. Doesn’t hurt and showed up about two weeks ago. Has small red blood vessels coming out. Didn’t have a head like a pimple. I got some puss out and thought it would heal up and go away after I cleaned and put antibiotic ointment on it. But it’s not. Now nothing is coming out. I’m still breastfeeding and not having issues and it’s on the side of my right breast. Nothing has irritated it like my bra or anything. Scaring myself because of course I googled and it keeps bringing up breast cancer. There isn’t a lump really. Anyone know what this is ?

My doctor will look at it at my baby’s 6 month appointment. But I’m just nervous.
